一個Email保護的小工具

博友們好多已經把自己的連絡方式放在自己的部落格上了，但是容易被Spam網站或者機器人擷取而經常發一些垃圾或者病毒。所以有很多方法處理，一種就是對pattern的這個破壞，例如將@符號替換掉。方便些，但是不是很徹底解決的。今天搜CMU的一個牛人的時候，發現其Email就用了這個工具-CAPTCHA，所以覺得很好玩，也拿來分享下吧。

使用也很方便，你可以這裡輸入想要保護的Email，提交之後就會產生html的代碼，你就可以在寫Email地址的地方用了。可以輸入驗證碼擷取你的比較重要的Email了，個人覺得很方便，實用。

=====================================

eCAPTCHA is a free CAPTCHA service that helps to digitize books, newspapers and old time radio shows. Check out our paper in Science about it (or read more below).

A CAPTCHA is a program that can tell whether its user is a human or a computer. You’ve probably seen them — colorful images with distorted text at the bottom of Web registration forms. CAPTCHAs are used by many websites to prevent abuse from “bots,” or automated programs usually written to generate spam. No computer program can read distorted text as well as humans can, so bots cannot navigate sites protected by CAPTCHAs.
